<title>High Availability</title>

<para>Several aspects of an OpenStack Networking deployment benefit from high-availabilty to
|
||
withstand individual node failures. In general, neutron-server and neutron-dhcp-agent can be
|
||
run in an active-active fashion. The neutron-l3-agent service can be run only as
|
||
active/passive, to avoid IP conflicts with respect to gateway IP addresses.</para>
